Hi
I am trying to make a filter that will redirect all request that don't have a autheticated
attribute set, to be redirected to the login page.
Somehow my filter does not work properly even though it still is a very basic implementation
that
does nothing besides a few system out prints.
The only confirmation i get that this filter is in fact loaded into tocat, is that during
startup my constructor is called. I know that since the system out call writes to the console.
The filter is supposed to take all request to the site since the url-pattern is set to /*
Here is the code for the filter :
public class BidFilter implements Filter
{
private FilterConfig filterConfig;
public BidFilter() {System.out.println("Filter Constructor");}
public void init(FilterConfig f) {}
public void doFilter (ServletRequest request, ServletResponse response,
FilterChain chain)
{
try
{
System.out.print ("Within Bid Filter ... ");
System.out.println ("Filtering the Request ...");
chain.doFilter (request, response);
System.out.print ("Within Bid Filter ... ");
System.out.println ("Filtering the Response ...");
} catch (IOException io) {
System.out.println ("IOException raised in BidFilter");
} catch (ServletException se) {
System.out.println ("ServletException raised in BidFilter");
}
}
public FilterConfig getFilterConfig()
{
return this.filterConfig;
}
public void setFilterConfig (FilterConfig filterConfig)
{
this.filterConfig = filterConfig;
}
public void destroy() { }
}
And here is the web.xml file for the filter :
?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<display-name>Filter Request</display-name>
<description>The Secure Server</description>
<filter>
<filter-name>BidFilter</filter-name>
<filter-class>Bid.BidFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>BidFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<session-config>
<session-timeout>1</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
</web-app>
Any help would be very appreciated
regards
Abid
